Seattle FilmWorks Image (.sfw)

The SFW file extension stands for Seattle FilmWorks Image, a proprietary bitmap image format created by Seattle FilmWorks, a company specializing in film processing and digital imaging. Although the company is now defunct, SFW files can still be viewed using specific software or converted to standard formats like JPEG. This format is not widely supported by modern image editing software.

Portable Floatmap (.pfm)

The Portable Floatmap (PFM) file format, also known as Portable FloatMap, is an image file format designed to store High Dynamic Range (HDR) images using floating-point values. Developed in the spirit of the Portable Pixmap format, PFM files contain image data with resolutions and byte order specified in the header. This format is particularly useful for applications requiring precise image data, such as computer graphics and image processing. PFM has been widely adopted in the IT industry for its ability to handle a wide range of pixel values beyond the standard 0-255 range, making it ideal for HDR imaging and other advanced visualizations.
